The Microsharp product range and product design capabilities

Display Applications

  • Controlled angle of view diffusers for use in autostereoscopic (3D)displays.
  • Displays in which a narrow angle of view is required
  • Applications where 2 different data sources need to be seen from the same screen depending on the angle of view
  • Lenticular Diffusion is used to increase the uniformity of light output and avoid the lightsource image appearing on the screen

Lighting Applications

Lenticular films can be used as highly efficient “Lenticular Diffusers” in conjunction with LED light sources. Applications include:

  • Architectural lighting
  • Large area lighting
  • Ceiling lights
  • LED strip lights

Principle of autostereoscopic displays

Autostereoscopic Displays

Transparent lenticular film material has a very long history in its usage in autostereoscopic imagery - the production of images with a different appearance when viewed from different directions. The results are achieved by printing strips of alternating imagery under the lenticular film which projects the different strips in different directions. Therefore, each eye is able to see a different image, and the image seen change as the viewing direction changes.

 

Schematic view of how a viewer perceives an autostereoscopic picture.

To form an autostereoscopic picture, part of the light diffused by the picture is seen only by the left eye while the right eye perceives a different part of the picture so the viewer can appreciate the depth. The use of lenticular lens to achieve such autostereoscopic effect is long known. The lenticular lens is employed as an angular filter to direct distinctly the light of the left and the right image.

Lenticular Diffusers

Diffusers are used for a variety of purposes:

  • to hide a light source or to eliminate the image of its filament;
  • to make the appearance of a viewing screen more uniform;
  • or to spread the light from a source into a defined angle.

Lenticular films defocus collimated light sources. A suitably designed lenticular film can act as an asymmetrical diffuser to generate wide angles of view in a chosen dimension. Lenticular films can be overlaid to control diffusion in both dimensions.

Development and Supply of Lenticular films

Microsharp's can design and develop structures to clients' specific needs. Structures can be produced with pitches of between 20 and 150 microns. 

Microsharp is able to design films that have specific diffusion or autostereoscopic properties.
